This paper proposes a method on high-frequency vibration compensation of helicopter-borne synthetic aperture radar (SAR) in terahertz band. The SAR signal model with platform vibration is established based on the mechanism of a helicopter's vibration. Then successive Doppler keystone transform (SDKT) is used to correct the range cell migration induced by the vibration. Finally, the analytical formula of the platform vibration phase error is given as well as its compensation to achieve a focused image.
